Q. In case of builders, the input tax credit is limited to the number of flats sold before getting the completion certificate. However, at the time of availing the credit (while the project is ongoing) it is not certain as to how many units will get sold before completion. Hence, the total input credit is availed. Now, when the completion certificate is obtained, there can be some units unsold, on which no GST is to be paid. Our question is: How much GST is to be reversed at the point of completion? Should total credit be apportioned based on completed unsold flats and flats sold before completion, or should the input tax related to procurements after completion be taken into consideration?
